The effort to rescue 33 trapped Chilean miners went into high gear on Tuesday as a 31-ton Raise Borer Strata 950 drill began to work round the clock drilling down to the men, a half-mile under the Atacama Desert. The drilling will take about four months and even then, the resulting hole will only be large enough to haul up one miner a time. Officials estimate that once the hole is dug it will take three-to-four days to extract all the men. Chilean President Sebastián Piñera has dubbed the mission "Operation San Lorenzo," a reference to the patron saint of miners. The drill, which was shipped to the site in pieces, bore a preliminary hole Monday evening. Drill operators now expect to carve out about 15 meters of rock per day. The process could take until after Christmas to drill a two-foot diameter hole down some 2,300 feet and install cages to lift the miners to the surface, according to Mining Minister Laurence Golborne. After everything is installed, rescue workers will descend into the mine to help the men into the cages. Lifting each man to the surface will take roughly 2 hours. "More important than time is that we avoid mistakes," Mr. Golborne told reporters today outside the mine in northern Chile. 3 rescues Chilean miners could take hope from Yet time is very much a factor. Golborne said there are about 10 backup options currently on the table for the rescue, ordered by President Piñera to speed the process as much as possible. If the Strata 950 should fail, then a backup Strata 950 drill is waiting in the wings. If the backup drill also fails, a T-130 drill could be used to widen an already existing hole that reached the miners shortly after they were found. “The Strata has begun digging, an important first step,” Golborne said. “The installation phase was very complex, which was done in record time considering what it normally takes to install this machine.”
